Ok, I have a Razr with a camera but no video camera how do i go about getting a software update ??

I have a Cingular Razr. My Razr haves a digital camera camera on it. I heard I can get a software upgrade so that I can get video camera. Where do I go? What do I do? Do I have to get a new Razr just to have a video camrea, or can it be added on to my Razr I have now with software??

I have the black Razr from Cingular and I like it.
